recommend one size larger than weight

our 4yr old is 43lbs. He wears the XL because they hold the perfect amount for him and his night time accidents.

We're sorry to hear the Ninjamas Nighttime Underwear didn't fit your grandson as you'd expect, Becky.

So we can see how best we can help, please call us at 1-833-646-5262 when you have a moment.

I have a special needs son who is the size of a 7 year old. He wears these at night and loves that they don't "look like a baby diaper". As for absorbency...welp one just went through the washer and didn't bust!

reply from Ninjamas

We know how frustrating leaks are, Kaylynn, so we're very sorry for this experience with Ninjamas. We're here to help and would like to share that size and fit are a huge part of finding the right diaper for your baby, and as you know, babies come in all different shapes and sizes, so diapers fit every baby differently. Our diaper sizes are organized by weight, and since no two babies are the same shape, you will notice some overlap between sizes. In most cases, your baby should be within the weight range for the size you are using, but if leaking is occurring, it may be an indicator to go up a size. So we can help get you and your baby back to leak-free days and nights, please give us a call at (800) 726-7377.

Less leakage than competitor. Comes up higher in front which is good for boys.

I prefer Ninjamas over "Goodnights". They are more fitted around the legs which helps with leaks. Goodnights leak and in my experience.
